一、甜瓜甜瓜地膜覆盖栽培现已普遍在法国应用。使用的薄膜有透明膜、黑色膜和烟灰色膜。薄膜打孔,也可不打孔,不打孔时在有暴雨的地区薄膜上容易积水。黑色膜能抑制杂草生长,促进早熟;透明膜和烟灰色膜也能取得促进早熟的效果。应根据不同的薄膜取不同的管理措施。Carolus 等人于1963年谈到,覆盖无孔薄膜杂草生长茂盛,甜瓜的发育受影响,如果覆盖的薄膜两端用土封口,杂草的生长势大大减
First, melon melon film mulching cultivation has now generally applied in France. The films used are clear film, black film and sooty film. Film drilling, but also do not punch, do not punch when there is rain in the area of the film easily water. Black film can inhibit the growth of weeds, promote early maturity; transparent film and smoke gray film can also get the effect of promoting premature. Should be based on different films to take different management measures. Carolus et al., In 1963, talked about the growth of non-porous filmy weeds that affected the development of melons. If both ends of the covered film were sealed with soil, the growth of weeds was drastically reduced
